Geologic Periods Computer Borders This table is arranged with the most recent geologic periods at the top, and the oldest at the bottom. the height of each table entry does not correspond to the duration of each subdivision of time. The geologic community broadly recognizes the anthropocene as a proposed new time interval of earth history, partly coincident with the holocene. currently, the anthropocene has an informal designation, with a proposed age span extending from the present to a beginning point between ca. 15,000 yr b.p. and as recent as 1960 ce.
Geologic Eras And Periods The geologic time scale, as shown above, documents intervals of geologic time relative to one another, and has been continuously developed and updated over the last two centuries. And because almost every period of the phanerozoic is represented along that section through wales and england, it is a primitive geological time scale. figure 8 6 2: william smith’s “sketch of the succession of strata and their relative altitudes,” an inset on his geological map of england and wales (with era names added).

Most of the boundaries between the periods and epochs of the geological time scale have been fixed on the basis of significant changes in the fossil record. for example, as already noted, the boundary between the cretaceous and the paleogene coincides exactly with the extinction of the dinosaurs.
